I just finished reading a section of our class book, Social Determinants of Health, a Canadian Perspective from Dennis Raphael. A few thoughts came to mind as I was reading the chapter on Precarious work and the Labour Market and how it affects our sense of employment security in Canada.
The thing that came to mind and kept nagging at me the whole time I read and took notes is that we are evaluating insecurity of employment based on our opinions of what a good employment actually is.  Meaning that my generation, and the one before me, we have been raised to believe that full time employment with one company, one pay check, a pension plan and some upward mobility is important to our sense of security and therefore the preferred employment styles.  But the landscape of employment and career types have greatly changed, for example, I have 3 jobs, one as a self employed RMT, one as an faculty for Langara College and one as a contractor for the College of Massage Therapist of BC as a consultant.  All three jobs add up to full time work.  My brother and sister-in-law both have a very similar situation.
I now see this as not only normal, but as giving me a sense of security because if one job falls through, I have the other two to keep my family afloat.  It does have moments of feeling very overwhelming, especially when deadlines in both jobs for which I have bosses end up being to close to each other and it is difficult to meet the demands.
So for me, this is both a good thing and a difficulty that I have adapted to, but when I talk to my children, this is the only employment landscape they know of.  For them, multiple part-time jobs with different industries is not only normal, but acceptable and actually desirable.  For example, I was having a chat with my teenage son, I casually asked him what he thought he might want to do later in life, his reply:  "Well I think I would like to start with..."  Yes, those were his words, I would like to start with.  He already is planning on multiple career paths/changes for his life long working experience.  To him, it's a no brainer that you are not expected to spend your entire career with one company doing one job, that thought is probably stressful to him.  It's not entirely surprising being that he is raised by a woman who started as a nurse, changed to an RMT, added teaching and consulting on the side and is now going back to school toward another new career path.  His father has had 5 completely different jobs since he was born 16 years ago.  He only knows this new form of employment landscape.  So as we evaluate this "precarious" work as a source of insecurity for Canadians at the moment, I suspect that in a few years, this might be completely different.
